A simple word scrambling alorithm.

Scrambler

A simple little word scrambler built in the Intermediate Student Language.

The Algorithm

• Take all vowels in the word and replace them with the next vowel in the list (A, E, I, O, U, (Y)), with 'Y's only being counted as a Vowel if it is inside the String, and is not to be used as a replacement
• Iff there is a 'Y' in the word, then replace it with 'A' (case-insensitive), with that new 'A' becoming the new candidate for insertion
• Insert the last vowel replacement 2 positions after itself
• If the last replacement is the last 1String in the list, then do nothing extra
• Only perform insertions if the entire current String is alphabetical
• Unless the entire currnet String is upper-case, ensure the insertion is lower-case

Examples

• Kensington -> Kinsongtunu
• Sponge -> Spungi
• Empty -> Impta
• Plank -> Plenek
• About -> Ebuata
• Hello -> Hillu
• He, -> Hi,
• (Wow) -> (Wuw)
• HELL -> HILIL
• Hell -> Hilil

Functions

To use the algorithm, call the function (scramble-main String).

Note

This program assumes that you are passing in a proper English phrase or sentence (with the exception in acronyms or capitalized words). As a result, Strings with typos or seemingly misplaced capital letters would return a slightly unexpected result.

Ex.

• WOW -> WUWU
• wOw -> wUwu
